Case Study on Cut-off Grouting for Subsea Tunnel Construction Using Automated Multi Grouting System and Grouting...
Abstract: Cut-off grouting in the construction of subsea tunnels has been regarded as a key factor that causes a successful construction of an underground space. An Intelligent Multi Grouting system, IMG, which can control the pressure and flow rate of the grout automatically, and a grouting design software which can be conveniently used to provide a package of design of grouting patterns have been...

Cutting tool wear evaluation for soft ground TBMs
Abstract: TBM cutter life and wear evaluation in soft ground are important issues, especially in pressurized face tunneling with soft ground TBMs for which the planning of costly interventions becomes crucial. This paper presents the evolution and latest developments of different methodologies and tests in cutter life evaluation in soil with a major focus on identification of the main influential...

Design of Tunnel Lining Insulation Based on the Numerical Analysis and the Measurement of Temperature in Tunnel
Abstract: In this paper, a few freezing cases of road tunnels were reviewed, and it was concluded that the freezing protection is necessary. In order to characterize the thermal distribution in the tunnel, measurements were performed on the following area of a road tunnel during winter; the temperature distribution along the tunnel axis, the internal temperature of the lining and the temperature...

New abrasion test (NAT) for the evaluation of hard-rock TBM cutter life
Abstract: Despite the presence of some rock abrasivity tests, the tunneling industry still seeks for a reliable method to simulate the real TBM excavation condition and to connect the test results with the cutter life data from the field. New abrasion test (NAT) is a test developed in Hyundai Engineering and Construction to improve some of the deficiencies of the previously developed hardrock abrasivity...

Numerical Analysis of PSTM (Pressurizing Support Tunnelling Method) using Reinforced Steel Beam for obtaining...
Abstract: With the expansion of infrastructure such as railroad and expressway network, in recent years, the application of the trenchless tunnel method to cross under road is increasing. In this regard, various trenchless methods have been developed by using different roof structures, each of which uses large stiff structure. These conventional trenchless methods have some features in common as follows;...

Rotary Cutting Test for Hard Rock TBM Performance Evaluation
Abstract: TBM has many advantages over traditional methods especially for longer drives when the higher excavation rate can trim a large amount of cost and shorten the construction time in comparison with traditional tunnelling methods. Throughout the history of application of TBMs, major enhancements have been achieved especially for cutting efficiency in both cutting geometry characteristics and...
